Born March 22, 1930 in New York, Stephen Joseph Sondheim was the son of Etta Janet and Herbert Sondheim. His parents were a clothing designer and a dress manufacturer, respectively. The two divorced early in Sondheim’s adolescence. After the divorce, Sondheim moved to Bucks County, Pennsylvania and attended a private Quaker school — where he wrote his first musical: Bye George. After graduating in 1946, he attended Williams College until 1950.

At the age of 10, Stephen Sondheim became friends with James Hammerstein, son of Oscar Hammerstein II, and became a mentee and protégé of the lyricist and playwright. Sondheim spent time with the composer as he worked on plays like Carousel and Allegro - watching his mentor create both greatly successful pieces and struggle with pieces that had less acclaim. Sondheim also stated that had it not been for Hammerstein insisting, he would not have written the lyrics for West Side Story or Gypsy. He joked that “had Hammerstein been a geologist” - he might have been one too. While at college, Sondheim was also mentored by American composer Milton Byron Babbitt, who encouraged him to study and dissect both musical theatre giants — Rodgers and Hart, George Gershwin, and the classical music greats — Mozart, Beethoven, etc.

After college, he spent a few years writing for the television show Topper — a sitcom about a couple finding out their home is haunted by the previous owners and their dog who died in a skiing accident — and then went on to write incidental music for the play The Girls of Summer — a play about a 30 something woman who suddenly finds herself in a complicated love triangle after pushing romance out of her life for years. After meeting Arthur Laurents at a party, and with an endorsement from Oscar Hammerstein II, Sondheim had his big break, writing the lyrics for West Side Story which premiered in 1957. Two years later, Laurents and Sondheim worked together on the hit Gypsy.

Stephen Sondheim went on to write 23 musicals, win a Pulitzer, an Oscar, a Presidential Medal of Freedom, a Laurence Olivier Award, eight Grammys and eight Tony Awards — more than any other composer. Sondheim is considered one of the most important American composers — contributing to the sound and story of the American musical theatre. Frank Rich of the New York Times described him as “now the greatest and perhaps best-known artist in the American musical theatre.” Sondheim passed away November 26, 2021 at the age of 91.
